To Calculate Current You Can Use The Following Calculation

Answers

Answer 1

Answer:

It depends on the circuit. Many would answer with Ohm's law, but that is not accurate because Ohm's law is applicable only to a particular case:

Ohm's law I = U / R; where R is a constant linear resistance, U a voltage, I a current, and no other impedance is in the system.

Ohm's law allway applies to linear constant resistances, but there is much more to an electrical system than just plain resistances.

Besides linear constant resistances there are: inductances, couppled inductances, capacitances, non linear behaviour, voltage and current sources, radiation behaviour, etc.. They all play a role t

Explanation:

Calculating electrical current in D C circuit : I (Intensity of current) =E (electromotive force) / R (Resistance of circuit).(ohm’s law)

Calculating electrical current in A C circuit : Ohm’s law for Capacitive circuit : The current in a capacitive circuit is directly proportional to applied voltage and inversely proportional to the capacitive reactance. I = E/Xc.

If there is a resistance in series with the capacitor,then I = E/Z , Z is the total impedance of, To find Z , square root of R square + Xc square.

Calculating electrical current in A C circuit,: Ohm’s law for Inductive circuit :

I = E/ XL ; 0r square root of R square + XL square =Z impedance. I + E/Z .

Engineers help to develop the physical infrastructure we all rely on – transport networks, roads, bridges, water and energy supplies, and waste management. We also have them to thank for our digital infrastructure – communications and navigation networks that are part and parcel of urban life. Engineers play a huge role in healthcare and food, and in manufacturing and research.

And by building this infrastructure, engineering has had a much wider and more lasting impact – it has helped to fuel economic growth. Well-built housing and sanitation improves the quality of life of all residents. Good transport links make it easier for businesses to trade their goods, and enables the workforce to be more mobile. High-speed internet can boost productivity, improve efficiencies, and help an organization to look beyond its local or national borders… the list is endless.

40. Evaluate f (x2-2xy)dx +(x2y+3)dy around the boundary of the region defined by y2 = 8x and x = 2
(a) directly, (b) by using Green's theorem. Ans. 128/5
(TT.2)
41. Evaluate f (6xy - y2) dx + (3x2 --- 2xy) dy along the cycloid x = 6 - sin 6, y = 1 - cos 6.

Answers

(40) It looks like the line integral is

[tex]\displaystyle \int_C (x^2-2xy)\,\mathrm dx + (x^2y+3)\,\mathrm dy[/tex]

where C is the boundary of the region D,

[tex]D = \left\{(x,y) \mid \dfrac{y^2}8\le x\le2\text{ and }-4\le y\le4\right\}[/tex]

(a) To evaluate the line integral directly, split up C into two paths C₁ and C₂, parameterized by

C₁ : x = t ²/8 and y = -t, where -4 ≤ t ≤ 4

(the y component is negative to make this path have a positive/counterclockwise orientation)

• C₂ : x = 2 and y = t, where -4 ≤ t ≤ 4

Then the line integral over C is the sum of the line integrals over C₁ and C₂ :

[tex]\displaystyle \int_C = \int_C \left(\left(x(t)^2-2x(t)y(t)\right)\dfrac{\mathrm dx}{\mathrm dt} + \left(x(t)^2y(t)-3\right)\dfrac{\mathrm dy}{\mathrm dt}\right)\,\mathrm dt \\\\ = \int_{-4}^4 \left(\left(\frac{t^3}4+\frac{t^4}{64}\right)\frac t4 - \left(3-\frac{t^5}{64}\right)\right)\,\mathrm dt + \int_{-4}^4 (4t+3)\,\mathrm dt \\\\ = \int_{-4}^4 \left(4t+\dfrac{t^4}{16}+\dfrac{5t^5}{256}\right)\,\mathrm dt = \boxed{\frac{128}5}[/tex]

(b) Using Green's theorem, we have

[tex]\displaystyle \int_C (x^2-2xy)\,\mathrm dx + (x^2+3)\,\mathrm dy = \iint_D \frac{\partial(x^2y+3)}{\partial x} - \frac{\partial(x^2-2xy)}{\partial y}\,\mathrm dx\,\mathrm dy \\\\ = \int_{-4}^4 \int_{y^2/8}^2 (2xy+2x)\,\mathrm dx\,\mathrm dy = \boxed{\frac{128}5}[/tex]

# # #

(41) I assume you meant to use θ in the parameterization, and not 6, so that C is parameterized by x = θ - sin(θ) and y = 1 - cos(θ). There's no range given for θ, so I'll just assume 0 ≤ θ ≤ π.

Then ... (for some reason, the math text won't render properly. I've attached the computation as an image)

(where s = sin(θ) and c = cos(θ))

Improvements to brake systems are

Increase in disc radiusIncrease in caliper piston areaLine pressureThe friction coefficient between the pad and the rotorWhat is a brake system?Converts the thermal energy through friction, and the brake system takes the kinetic energy of your moving vehicle.Larger discs will permit for more brake torque as the brake pad will apply pressure at a larger radius, permitting for a higher moment.Increasing the size of the pistons means you have more area to put in a specific pressure. If the pressure remains the same and the area increases, the force applied will be increased.Push your foot harder, and the car brakes harder due to this the line pressure increases. Self-explanatory, but if you can increase the friction between the pad and the rotor, you can increase the braking torque.

2

(b) (A3.C)
16

(c) (75.16)
8

(d) (ABCD)
16

Answers

(a)

11001.1011₂ = 1×2⁴ + 1×2³ + 1×2⁰ + 1×2 ⁻¹ + 1×2 ⁻³ + 1×2 ⁻⁴

… = 16 + 8 + 1 + 1/2 + 1/8 + 1/16

… = 411/16

(b) In base 16, we have A₁₆ = 10 and C₁₆ = 12, so

A3.C₁₆ = 10×16¹ + 3×16⁰ + 12×16 ⁻¹

… = 160 + 3 + 12/16

… = 2620/16 = 655/4

(c)

75.16₈ = 7×8¹ + 5×8⁰ + 1×8 ⁻¹ + 6×8 ⁻²

… = 56 + 5 + 1/8 + 6/64

… = 3918/64 = 1959/32

(d) B₁₆ = 11 and D₁₆ = 13, so

ABCD₁₆ = 10×16³ + 11×16² + 12×16¹ + 13×16⁰

… = 40960 + 2816 + 192 + 13

… = 43981

how is a electrical resistance similar to the diameter of a pipe of water

Answers

Answer:

The resistance of the flow of charges in an electric circuit (electrical resistance) is analogous to the frictional effect between water flow through a pipe and the pipe's surface

Explanation:

In comparison to its similarity to the diameter of the pipe affects the flow of water and acts a a factor affecting resistance so are there factors affecting electrical resistance.

in an electrical circuit:

the total length of the wire is to the length of a pipe of water

the cross-sectional area of the wire is to the diameter of a pipe of water.

Thus, the cross sectional are affects the amount of electrical resistance. Wider wires have wider cross-sectional area and vice versa. Also, water will flow (i.e. current) through a wider pipe (i.e. large diameter) at a faster rate than a narrow pipe (i.e. small diameter). This is due to the lower amount of resistance offered by the wider pipe.

in the same manner, the wider the wire, the lesser the electrical resistance to the flow of elsctric charge and vice versa for thiner wires.

An engineer is a person who designs, builds, and maintains machinery and structures like bridges, railroads, and highways using scientific knowledge.

The word engineer, from which the term engineering is derived, was first used in 1390 to refer to "a constructor of military engines." The term engine'er literally means "one who operates an engine."

In this now-outdated meaning, the term "engine" refers to a military machine, or a mechanical device employed in battle.

An engineer is someone who practices engineering, and those who are qualified to do so may hold more official titles like "Designated Engineering Representative," "Professional Engineer," "Chartered Engineer," "Incorporated Engineer," "Ingenieur," or "European Engineer."

Teams of engineers design and deploy various goods utilizing predetermined procedures.
